Adjust the Drive Belt Tension

These instructions pertain only to Cyberware Head & Face (Model PS) 3D scanners.

A user may diagnose this problem when he/she notices that there are many wide vertical lines (belt is too loose) or many tightly-spaced vertical lines (belt is too tight) in a dataset. The user should first verify that the scanner is level and that the platform feet are firmly in contact with the floor before proceeding with this procedure.

  1. Turn off the power at the power supply.
  2. Find the leg that the motor is secured to. Locate the belt cover.
  3. Remove the belt cover (if there is one) using an M2.5 hex wrench.
  4. Loosen the four motor bracket bolts that secure the motor assembly to the motion platform leg (two on the top of the leg and two on the side of the leg) using an M5 hex wrench.
  5. Adjust the tension by pushing/pulling the motor assembly. The correct belt tension will allow an operator to move the belt (at the middle point between the motor pulley and the large platform pulley) 1-2 cm. Be very careful not to get the tension too tight, as this will cause vertical lines to appear in the scanned data.
  6. Secure the motor assembly by tightening the four motor bracket bolts using the M5 hex wrench.
  7. Replace the belt cover and secure it with the M2.5 screws (if included with the scanner).
  8. Turn on the power supply.
  9. Home the scanner. Check for a smooth homing sequence.
  10. Scan a subject to verify that the data is smooth.
  11. Adjust further, if necessary.
